Continuous glucose monitoring and automated insulin delivery systems in the management of diabetes among individuals with chronic kidney disease on dialysis.

Abstract

Purpose of review: To describe the current evidence and emerging role of continuous glucose monitoring (CGM) and automated insulin delivery (AID) systems in the management of diabetes among individuals with advanced chronic kidney disease (CKD) undergoing dialysis.

Recent findings: Recent studies have shown that CGM provides accurate and clinically useful glucose data in people with advanced CKD requiring dialysis. CGM enables the detection of glycaemic variability and hypoglycaemia patterns that are often missed by traditional monitoring methods, such as capillary blood glucose testing and haemoglobin A1c. While observational studies show benefits, randomised controlled trial data are limited. Early trials and case series suggest that AID, especially fully closed-loop systems, may improve glycaemia in dialysis-dependent individuals with diabetes, though evidence is currently sparse and primarily focused on type 2 diabetes. Several ongoing and planned studies aim to address these knowledge gaps.

Summary: CGM represents a valuable tool for improving glucose management and safety in people with diabetes and advanced CKD, but barriers to widespread use, such as cost, access, and healthcare provider familiarity, remain significant. AID technologies show promise but require further evaluation in this population. Future research should prioritise long-term outcomes, cost-effectiveness, and patient-reported outcomes to support the integration of these technologies into routine care for this high-risk group.
